Temperature Controller iB6 / iB12

1.0 Introduction

1.4 What Happens When You Power Up the Controller

When an iB6 or iB12 Temperature Controller is powered up using the switch on the back, all

LEDs and all elements in the LCD display light briefly, and then software versions (of the display

and the controller hardware) are displayed.

At the conclusion of the startup process, the process values and setpoints for all zones are

displayed. Only the green LED for the display unit of measure (Celsius or Fahrenheit) is lit.

All zone outputs will be off because the unit starts up with all zones in the Idle state.

Briefly pressing the run/idle button on the front of the case puts all zones that are currently

Idle in the Run state. (Pressing the button again for at least two seconds puts all zones in Idle.)

In each zones column of LEDs, the green LED in the closed loop or open loop row is lit to

indicate the type of control.

The green LEDs in the output row indicate whether the zones outputs are on (LED lit) or off.

For more information about the user interface, see the Section 3.

When zones go into the Run state, the effect on each zones output depends on the value of the

Startup Mode parameter configured using the Control Config menu.
